Title: An improved device for use in cutting sheet material also applicable for use as a scraper
IPC: B26B5/00
Filed: 1944-08-22
Abstract: 596,373. Hand knives. GREENWOOD, J. E. Aug. 22, 1944, No. 15980. [Class 30] [Also in Groups VIII and XXIII] A device for cutting sheet material such as paper, cardboard, canvas, cloth or oilcloth or for use as a scraper comprises a main plate a attached to a handle d and having a pair of screwed studs f adapted to pass through the usual holes in a razor blade c and through slots in a clamping plate b which is also provided with a slot b<2> extending inwardly from one edge of the plate. The device is shown in Fig. 1 arranged as a cutter in which the sheet material entering the slot b2 is pressed against the edge of the blade c. The device is converted into a scraper bv turning the plate b so that the opposite edge to the one near the slot b<2> is adjacent the operative edge of the blade, a small part of the blade projecting beyond the edges of the plates a, b. The slots in the clamping plate b which receive the studs f are arranged so that when the device is assembled as a scraper, the clamping plate e may be adjusted so that its edge overlaps and guards the edge of the blade when the device is out of use. Specification 216,433, [Class 61(ii)], is referred to.

Abstract: 527,137. Shot-gun cartidges. GARKOVENKO, W. DE. May 31, 1939, No. 15996. [Class 9 (i)] Concentration of the shot charge in flight is regulated by enclosing the charge in a light fabric envelope 1, with open front end 2, and connecting a cardboard or like disc 4 at the base of the bag by a cord 5 to an under-shot wad 6. Wads of variable sizes and forms are used to produce varying dispersals of the shot, and the size of the aperture 2 and tautness of the envelope 1 may be varied to the same end. Apparatus for making and filling the envelope 1 and assembling the washer 4 and connected wad 5 is also described. The blank for the envelope 1 is a circular disc which is creased and then wrapped in spiral folds around the end of a mandrel 11, Fig. 5, by a pronged tool applied with a twisting movement to the end of the mandrel. Two rings 16, 17 are then passed on to the mandrel, the first being a close fit to tension the fabric. A plunger 12 within the mandrel is advanced by a hammer blow to form the perforation 2. The mandrel is then withdrawn, and the envelope is mounted in position, while remaining within the ring 17, in a press in which it is filled with shot and the disc 4 with string attached to the wad 6 is inserted, and the envelope closed by a cord 3.

Abstract: 983,399. Transistor switching circuits. STANDARD TELEPHONES & CABLES Ltd. April 25, 1963, No. 16313/63. Heading H3T. In a circuit for producing a sequence of pulses of alternating polarity, Fig. 2c, a source of unidirectional pulses of frequency 2f, Fig. 2b, is connected to a switching circuit together with a source of switching signals of frequency f, Fig. 2a, the circuit being switched by alternate half-cycles of the switching wave so as to reverse the polarity of alternate pulses of the unidirectional pulse train to produce the sequence of Fig. 2c. The switching wave, Fig. 2a, is applied to terminals 4 and the unidirectional pulses, Fig. 2b, are applied to terminals 3, Fig. 1. The switching waveform is such that the amplitude of the voltage induced in each half of the secondary winding of transformer 5 is equal to or less than the voltage of source 8. Transistors 1 and 2 therefore conduct in alternate half cycles of the switching waveform, but only during the application of the pulses of pulse train, Fig. 26, so producing a train of alternately reversed pulses in the secondary winding of output transformer 6.

Abstract: 476,948. Television receivers. BAIRD TELEVISION, Ltd., and WILLANS, P. W. June 18, 1936, No. 16980. [Class 40 (iii)] Synchronizing signals produce a sinusoidal oscillation of the same or harmonic frequency whose maximum value is displaced in phase relatively to the synchronizing signals and which is used to trip a scanning oscillator. An amplitude filter 1, Fig. 1, isolates the synchronizing signals which are applied to a tuned circuit 2, 3 so that a sinusoidal current oscillation 7, Fig. 3, is produced. The corresponding voltage oscillation 8 occurs 90‹ out of phase and has its maximum displaced from the synchronizing signals 6. The voltage oscillation is taken from across either the condenser 3 or inductance 2 and is utilized to trip the scanning oscillator at the point 9. The voltage oscillation may also be derived from parallel tuned circuits 2, 3, 4, 5, Fig. 2. The tuned circuits may resonate at the frequency of the synchronizing signals or at a multiple thereof. Specification 472,686, [Group XXXV], is referred to.
